In April 2015, the Apache Flink community released Flink 0.9-milestone1 and announced various updates including a Storm compatibility layer and an interactive Scala shell. The community also engaged in multiple speaking events and initiated a Stockholm Flink meetup group while welcoming three Google Summer of Code students for specific projects. Upcoming events include a workshop in June and the Flink Forward conference scheduled for October 2015 in Berlin.
